7-Zip is thread-optimized, but it seems that this optimization is limited. Turbo_T_SERIES_4/201312/18/10034.html">Intel’s TurboBoost shows a nice performance increase here, indicating that fewer cores with higher frequencies still yield big payoffs.

Cinebench in single-threaded mode runs faster on AMD's Turbo Core than on Intel’s Turbo Boost. This is because Intel allows only a 266 MHz increase, while AMD speeds up three cores by a more significant 400 MHz.

There are no differences once we switch to the multi-threaded workload.
